Stop test-in-container trying to run other-OS binaries.

I noticed that, now that build-many-glibcs.py no longer copies glibc
|
|
|
d8307d |
sources, I was getting core dumps in my glibc source directories. The
|
|
|
d8307d |
cause appears to be, from the i686-gnu build:
|
|
|
d8307d |
|
|
|
d8307d |
for dso in ` env LD_TRACE_LOADED_OBJECTS=1 \
|
|
|
d8307d |
/scratch/jmyers/glibc-bot/build/glibcs/i686-gnu/glibc/elf/ld.so.1 \
|
|
|
d8307d |
/scratch/jmyers/glibc-bot/build/glibcs/i686-gnu/glibc/testroot.pristine/bin/sh \
|
|
|
d8307d |
[...]
|
|
|
d8307d |
Segmentation fault (core dumped)
|
|
|
d8307d |
|
|
|
d8307d |
In this case, the x86 architecture means the binary executes, but
|
|
|
d8307d |
dumps core rather than actually working.
|
|
|
d8307d |
|
|
|

Anything involving running the newly built glibc should only be done
|
|
|
d8307d |
ifeq ($(run-built-tests),yes). This patch conditions the relevant
|
|
|
d8307d |
part of the testroot setup accordingly.
|
|
|
d8307d |
|
|
|
d8307d |
Tested for x86_64, and with build-many-glibcs.py for i686-gnu.
